Replacing letters with numbers and symbols is also a predictable practice. Every password cracker is aware of these poor password practices. Frequent password changes trigger our laziness, so “password” becomes “password1” and “password2”. The optimal defense against this kind of attack is simply to not use a password on the list. Blocking the source IP address will result in a new IP taking up the attack, if it hasn't already distributed across 100s, or even 1000s, of IP addresses. Even when Security Information and Event Monitoring (SIEM) or User and Entity Behavioral Analysis (UEBA) systems are active, there are limited defensive actions. Sensibly, they will try each password against every account they are aware of-few systems track password attempts across accounts. If a password cracker only tries one password every 10 minutes per account, 100,000 passwords will take a long time. Password crackers can try passwords at a slow, measured pace to avoid triggering account lock-outs on individual accounts. Automated password cracking toolsets that will autonomously run the attack Time on their hands, as they often take a scatter-gun approach to gaining access.Ģ. This in-depth blog highlights password vulnerabilities and risks that give attackers an edge, and provides an overview of password cracking motives, techniques, tools, and defenses.Īttackers typically hold at least two advantages over defenders:ġ. This is why highly privileged credentials are the most important of all credentials to protect. When a compromised account has privileges, the threat actor can easily circumvent other security controls, perform lateral movement, and crack other passwords. Forrester Research has estimated that compromised privileged credentials are involved in about 80% of breaches. Passwords are typically paired with a username or other mechanism to provide proof of identity.Ĭredentials are involved in most breaches today. Credentials can also be stolen via other tactics, such as by memory-scraping malware, and tools like Redline password stealer, which has been part of the attack chain in the recent, high-profile Lapsus$ ransomware attacks.Ī password can refer to any string of characters or secret to authenticate an authorized user to a resource.
These password cracking tools may be referred to as ‘password crackers’. Password hacking uses a variety of programmatic techniques and automation using specialized tools. Password cracking (also called, password hacking) is an attack vector that involves hackers attempting to crack or determine a password.
